Open Ports on WWAN side of an AR300m


regarding to a nmap scan from the outside to the WWAN IP of an AR300m, I found some open ports I don’t know.

4004/tcp open pxc-roid
4005/tcp open pxc-pin

why are they open and which service are listening on this ports?


SSH to your router and type following:

netstat -nap | grep LISTEN

That will show you what process is listening on which ports.

Thank you tomsmith842,

but what ever it ist, it’s a default as I didn’t configure such ans the AR300m ist nearly Fresh setup. So why ist it there by default?
